ContraCon decontamination routine procedure:
Fig. 27:
The routine is divided into four phases. Each individual phase or se-
veral phases can be cancelled (i.e. skipped).
If the operating step ”Cancel ContraCon routine” is executed, the routine mo-
ves to the next program phase. To cancel the routine completely, the operating
step must be executed repeatedly until the remaining run time display shows
the value 0.
When the glass door is opened, this operating step cancels the routine
completely.
The remaining run time of the ContraCon decontamination routine designates
the period between the start or the current routine time state and the cooling down
to the preset temperature nominal value (± 2° C).
Heating phase: Remaining run time approx 25 hours
The work space is heated to a temperature of 90° C while an elevated relative
humidity is created. The current decontamination temperature is shown at the
temperature display.
Decontamination phase: Remaining run time approx 23 hours
After the decontamination atmosphere has been created, the decontamination
phase with a run time of 9 hours is started.
If the door is opened during this time, the decontamination routine is restarted
automatically as soon as the door has been closed.
Cool-down phase: Remaining run time approx 14 hours
The device cools down until the originally set temperature nominal value is
reached.
Postheating phase: Remaining run time approx 3 hours
During the postheating phase, condensate within the device is eliminated as far
as possible; remaining condensate accumulates at the bottom of the work space.
